CONTRACTORS TORCH.

Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed December 8, 1910. Serial No. 596,243.

To all whom it may concern.

Be it known that I, ALEXANDER F. JEN- KINS, a subject of the King ofGreat Britain, residing at Baltimore city, State of Maryland, haveinvented certain new and useful Improvements in Contractors Torches, ofwhich the following is a specification.

This invention relates to protectors for reflectors of the open fronttype used in connection with contractors torches, and the presentinvention has to do more particularly with improvements in the type ofdevice disclosed in United States Letters Patent No. 962,640, granted tome June 28, 1910.

The invention has for one of its objects to provide an improvedreflector protector whereby the reflector is more capable of standingthe rough usage to which reflectors attached to contractors lights aresubjected so that denting, bending or otherwise destroying the reflectorwill be effectively prevented, the reflector proper being incased in aprotecting shell or section of steel or other suitable metal.

Another object of the invention is the provision of an improvedreflector holder or extension piece which serves to effectively clampthe inner section or reflector proper and outer protecting section inplace and at the same time forms a device for attaching the reflector tothe burner and to protect the flame issuing from the burner from beingblown out.

Vith these objects in view and others, as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claims appendedhereto.

In the accompanying drawing, which illustrates one embodiment of theinvention, Figure 1 is a vertical central section of the reflector,protector and bolder applied to a burner. Fig. 2 is a perspective viewshowing the reflector, protector and holder separated from each other.

Similar reference characters are employed to designate correspondingparts throughout the views.

Referring to the drawing, A designates the reflector, which is providedwith a holder B that is detachably applied to the burner C, the latterbeing of that type whereby a jet of gas discharges from the nozzle 1 andburns openly in the atmosphere. This combination or arrangement of partsconstitutes the invention set forth in the Letters Patent hereinbeforereferred to, and to this combination an attachment or addition is madein the form of a protector for the reflector whereby the latter will notbe so liable to injury, as heretofore. These reflectors are usually madeof aluminum and are highly expensive. As contractors lights aresubjected to very rough usage in the hands of ordinary laborers,experience has shown that the reflectors being without a casing or otherprotection are in some cases render useless by becoming dented or bent,which destroys the reflecting qualities. Aluminum is especially usefulfor reflectors, as it takes a high polish, but the metal is soft andhence easily bent or dented. Therefore, it is the purpose of thisinvention to provide a protector which is attached or applied to thereflector in the form of an external cover therefor.

The reflector A is spun or otherwise shaped fro-m sheet metal, and theinner surface of the body 2 is highly polished. The protector 3 is spun,pressed or otherwise formed to snugly fit over the body of the reflectorand is held in place solely by the holder B, so that the latter performsthe double function of clamping the protector to the reflector andconnecting the latter to the burner. Besides preventing the denting orbending of the reflector, the protector permits of the reflector beingmade of sheet metal of lighter gage than heretofore, thereby cheapeningthe cost of the reflector. To stiffen the outer edge of the reflectorwhen made of thin metal, a peripheral external bead 4 is formed, whichis open at 5 so as to receive the marginal edge of the protector. Thereflector and protector are provided with openings 6 and 7,respectively, that register and it is in these openings that the holderB is received.

The holder 13 is a metal stamping of tubular form having cylindricalterminal portions 8 and 9, the latter being considerably reduced so asto fit longitudinally on the burner body C. These cylindrical portions 8and 9 are connected together by a frusto-conical portion 10 that housesthe tip or nozzle 1 of the burner. The enlarged end 8 passes into theopenings 6 and 7 of the reflector and protector and is provided with aperipheral flange 11 that engages the inner surface of the reflector.The portion 8 behind the flange 11 is provided with external threads 12on which screws a cylindrical clamping ring 13. This ring is also asheet metal stamping and is formed with a flange 14 which engages theouter surface of the protector around the opening thereof. These flanges11 and it of the reflector holder B clamp the protector and reflectortogether and hold their outer edges interlocked. Struck outwardly fromthe edge ring 13 opposite from the flange 14 are lugs 15 spaced apart soas to form convenient finger grips whereby the clamping ring can bescrewed or unscrewed when it is desired to detach the reflector sectionsfrom the holder to apply a different sized reflector, renew the parts,or for any other purpose. In the frusto-conical portion 10 of the holderB is an air inlet opening 16 for admitting air to the flame and thisopening is controlled by a valve 17 pivoted to the holder at 18. Thesmaller end of the holder B has a laterally stamped out hollow boss 19in which is threaded a. screw 20 for locking the holder B on the burner(l, the inner end of the screw binding on the burner.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention a i pertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.

Having thus described the invention, what I claim as new, is:

1. A reflector, and a device for attaching the same to a burner, incombination with a protector in the form of a shell fitted to theoutside of the reflector and held in place thereon solely by the saiddevice.

2. An open flame reflector, and a holder therefor having parts clampingthe reflector, in combination with a protecting shell fitted to theexterior of the reflector and held fixed thereto by the said clampingparts of the holder.

3. A reflector having a central opening, and a holding device extendingthrough the opening and having inner and outer ela1nping members, incombination with a protector fitt ed to the reflector and having an opening through which the said device passes.

a. A reflector having a central opening, and a holding device extendingthrough the opening and having inner and outer clamping nien'ibers, incombination with a protector fitted to the reflector and having anopening through which the said device passes, said protector beingengaged between the said inner and outer members of the device andclamped to the reflector thereby.

In testimony whereof I afiix my signature in presence of two witnesses.
